WebPurplemath. The domain of a function is the set of values which are valid inputs. For a polynomial function, the domain will always be "all x"; for a rational function, the domain will be all x-values which do not cause division by zero; for an even-index radical function (that is, for a square root, or a fourth root, or a sixth root, etc), the domain will be all x … WebOct 25, 2024 · In general, to find the domain of a rational function, we need to determine which inputs would cause division by zero. The domain of a rational function includes all real numbers except those that cause the denominator to equal zero. How To: Given a rational function, find the domain. Set the denominator equal to zero.
